Evil and non-evil Facebook buttons

Many websites now include Facebook buttons and widgets of various sorts. As a user, it is worth knowing that if you are logged into Facebook, many of those buttons and widgets can be used by Facebook to track your web use and link it to your real identity.

This site has a Facebook button, as well, but it is a graphic that loads from my own server. It does not allow Facebook to add to their trove of data.

That said, Google has its own massive data pile, which this site contributes to in obvious ways like content being indexed and less obvious ways like Google Analytics visitor tracking.

Internet purists lament that the new service spells the end of anonymity. That is a big minus if you are trying to organise protests on social-networking sites, which many in the Middle East have done. Or it can lead to self-censorship. Even TechCrunch has its doubts: most comments are now of the overly positive sort. Others say that by using the comment service, websites in practice hand over their most valuable asset: the community of users.

ShareMeNot is a Firefox add-on for preventing tracking from third-party buttons (like the Facebook “Like” button or the Google “+1” button) until the user actually chooses to interact with them. That is, ShareMeNot doesn’t disable/remove these buttons completely. Rather, it allows them to render on the page, but prevents the cookies from being sent until the user actually clicks on them, at which point ShareMeNot releases the cookies and the user gets the desired behavior (i.e., they can Like or +1 the page).

According to Australian technologist Nik Cubrilovic: ‘Logging out of Facebook is not enough.’ He added, Even after you are logged out, Facebook is able to track your browser’s page every time you visit a website. He wrote in his blog: ‘With my browser logged out of Facebook, whenever I visit any page with a Facebook like button, or share button, or any other widget, the information, including my account ID, is still being sent to Facebook.’ After explaining the cookies behavior he also suggested a way to fix the tracking problem: ‘The only solution to Facebook not knowing who you are is to delete all Facebook cookies.
